复杂地质条件下采煤掘进高强支护技术的研究

High Strength Support Technology for Coal Mining and Excavation under Complex Geological Conditions

高强支护技术具有稳定性高、经济性好、适应性强等一系列优势。屯兰矿12401工作面回风顺槽工程在复杂地质条件下联合应用了多种高强支护技术,建立了施工全过程的风险管理系统,充分发挥了围岩自承载功能,取得了较好的效果。

High strength support technology has a series of advantages such as high stability,good economy,and strong adaptability.The 12401 working face return air channel project of Tunlan Mine jointly applied various high strength support technologies under complex geological conditions,established a risk management system for the entire construction process,fully utilized the self bearing function of surrounding rock,and achieved good results.
